The skin is the body's largest organ, and dermatology is the branch of medicine dedicated to its health. A Doctor of Dermatology is a medical doctor (MD) with advanced training and experience in diagnosing and treating hair, skin, and nail conditions. Dermatologists also perform elective cosmetic procedures to help improve the appearance and health of hair and skin.
Some common conditions treated by dermatologists include:
Acne: Acne is a common skin condition that affects people of all ages. It occurs when the pores on your skin become blocked, trapping oil and dirt inside them. This can lead to redness, swelling, and small bumps filled with pus called pimples. Acne can range from mild to severe and may cause scarring if not treated properly.
Skin cancer (melanoma): Skin cancer is the most common type of cancer in humans, accounting for more than half of all cancers diagnosed. It occurs when cells in the skin grow abnormally and uncontrollably, often forming tumors or lesions on the skin's surface. Skin cancer can be caused by environmental factors, such as UV radiation from sunlight and tanning beds, and genetic factors that make a person more susceptible to developing it.
Psoriasis: Psoriasis is an autoimmune condition that causes skin cells to grow abnormally rapidly. This results in thick, scaly patches of skin known as plaques, which can be itchy, painful, and cause discomfort. While the exact cause of psoriasis is unknown, it has been linked to genetics and environmental factors such as stress or certain medications. It typically affects the elbows, knees, and scalp but can appear anywhere on the body.
Eczema: Eczema is a common skin condition that causes itchy, red, and dry patches of skin to appear on the body. It can affect people of any age and is more common in children than adults. Eczema is not contagious but may be triggered by environmental or genetic factors such as allergies, stress, weather changes, or certain foods. Symptoms range from mild itching to severe inflammation and discomfort.
Hair loss: Hair loss, also known as alopecia, is a common condition that affects both men and women. It can occur due to genetics, hormonal changes, or conditions like thyroid disease. Hair loss can be temporary or permanent and come in many forms, including thinning hair, bald patches, or complete baldness.
Rosacea: Rosacea is a chronic skin condition that causes facial redness and inflammation, typically in the cheeks and nose area. It can also cause other symptoms, such as acne-like bumps, visible blood vessels, facial swelling, eye irritation, or stinging sensations. The exact cause of rosacea is unknown, but it has been linked to genetics and environmental factors like sun exposure and certain foods or drinks.

In addition, many dermatology clinics offer elective cosmetic services to improve the appearance of the skin. For example, a dermatologist may provide a specialized skincare routine to combat aging and wrinkles or laser removal for unwanted hair.
A dermatologist is a medical doctor who specializes in the care of hair, skin, and nails. All Doctors of Dermatology have specific training to diagnose and treat conditions related to the skin organ. In addition to this specification, a dermatologist can undergo even more training to perform specialized care.
Subspecialties of dermatology include:
Pediatric dermatology: Pediatric dermatologists specialize in diagnosing and treating skin conditions in children. They treat conditions like birthmarks, warts, eczema, or psoriasis.
Dermatopathology: Dermatopathologists are doctors who specialize in both dermatology and pathology. This means they are trained to examine biopsied parts of the skin and write a biopsy report to determine the possibility of skin cancers (such as melanoma) or skin diseases (such as impetigo, vitiligo, or warts). In addition, some dermatopathologists undergo special training to perform Mohs surgery, a precise technique used to eliminate skin cancer cells. The dermatopathologist uses a scalpel to remove cancer on the skin, as well as a thin layer of skin below. Once removed, this tissue is taken to a laboratory for analysis. This analysis helps the dermatopathologist determine if all the cancer cells from the skin have been removed or if further surgery is needed.
Cosmetic dermatology: Cosmetic dermatologists specialize in aesthetic skin care, treating conditions including acne, wrinkles, sagging skin, or varicose veins. These doctors are trained to perform cosmetic procedures like filler injections for sagging skin, laser resurfacing, or chemical peels.
Dermatologists must complete four years of a bachelor’s degree, four years of medical school, an internship, and a three-year residency. After finishing their residency, a dermatologist can complete an exam to earn certification from the American Board of Dermatology. Board certification ensures that the dermatologist has the expertise and qualifications to treat skin, hair, and nail conditions. Most dermatologists can perform the various subspecialties of dermatology listed above. Still, if they believe that even more specialized care is needed, they will offer a referral to a dermatologist who can perform the necessary procedures.
